An FDA panel is not really concerned that drug-eluting stents might cause serious blood clots. There are two kinds of stents[7]: those that elute and those that do not. The latter are simple metal devices used to prop open arteries that are gunked up. The former release drugs and are far more popular. In fact, drug-eluting stents make up 90% of stents sold, which means about $6 billion a year in profits for the medical device industry.

So, the news[8]* that they might kill more than they should (remember, the FDA accepts a relative number of “oops” when approving a drug) is not making Big Pharma happy. Over at the Motley Fool[9], they’re surmising that the FDA will probably let it all slide. Poor Pfizer just lost torcetrapib[10], so maybe it’s a little bit of a pity party. At any rate, ateriosclerosis, which stents address, is almost entirely preventable with a good diet and daily exercise. Something to think about. Apples?

Will I Miss Out If I Never Eat a Kumquat?

Junior Apple Jessica B. wants to know if we need variety in our diets, after all. Good question, Jess (can we call you Jess?). That does seem to be one of the hallowed tenets of friendly nutritionists everywhere. It’s right up there with 8 glasses of water daily and flail-away-at-the-cardio-machine.

What we want to know is: what do we really know? For all of human history, people ate locally, seasonally, and their variety was often limited. Evidence indicates that cave-dudes and cave-ettes didn’t really struggle much with things like obesity and diabetes. As long as they weren’t wiped out by the latest glacier or wild boar attack, people were reasonably healthy on diets that centered around one or two fiber sources, some type of greens (anything from kelp in Japan to moss in Siberia), and a protein source or two (fish in New Zealand, reindeer in Finland). What do you all think about the variety debate? Get thee to the forum[11]!
